Quad-Core ARM CPU Support Found in Xcode, Quickly Removed by Apple
Apple looks to be experimenting with quad-core ARM CPU’s, possibly for future iPhone, iPad, and even MacBook Airs, as references in Xcodes default compiler reveal. This was first discovered by ArsTechnica, who proposes three possible scenarios for why the CPU support exists:
- Quad-core processor could be included in next-gen iOS devices like the iPad 3
- The quad-core chip could be coming to the MacBook Air (earlier rumors suggest a move away from Intel is possible)
- The CPU is being used for iOS and OS X prototypes
Ars concludes the third option is most likely, suggesting that Apple is using the CPU for prototypes:
“most probable in our opinion, is that Apple is using the Marvell chip in prototypes of future iOS device designs (or even an ARM-based MacBook Air that is rumored to exist somewhere inside One Infinite Loop) for testing purposes. An Armada XP-powered prototype logic board would allow iOS or Mac OS X software engineers to experiment with performance tuning and other optimizations”
Update: the references have since been removed from the second page as well.
